Application filed September 22, 19%. Serial naeaami.

To all whom it may concern:

lie it known that 1, Jumps F. YOUNG, a citizen of the United States, and a resident of ()watonna, in the county of Steele and State of Minnesota, have invented a new and Improved Flushing. Device for Water-Closet 'lhnks, of which the followingis a full, clear, and exact description.

The purpose of the invention is to provide an independent automatic locking device, adapted for use in connection with the customary float locking supply valve, and which, although it'ma-y be usedfor other purposes, is especially. designed to be.em-.

ployed in water-closet tanks.

This improved apparatus rovides a simple and economic means for ouble locking and compressing the packing of the supply valve, whereby to cause it to bear against the collar and hold it securely locked, so that even if the flushing valve were to leak and discharge all the water in the tank, it would not supply more water, unless it should be desired to flush the closet by intentional operation of the flushing lever.

A further feature of the invention consists in the employment of an auxiliary weighted locking lever that will cause the customary ball float supply valve to instantaneously close.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter particularly described and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

lneonnect-ion with my improved device I em loythe customary discharge valve A, for ushing purposes, having a proper seat A and a connection A with the closet bowl or-other article to 'be-fiushed. The valve A is operated by a strap or similar connection A, with a lever A of any desired type, fulcrumed upon a bracket 10 secured to the upper edge of the tank- A", and operated by an attached chain or cord A, or the equivalent of the same.

At the bottom of the tank A, suitably removed from the fiushin valve A, a casin 12 for an inlet or supp y valve,.is locate having a discharge nozzle 13 within the tank, and suitable connection 14, with a source ofiwater su ply. The nozzle 13 1s provided with a ange 13 which abuts against the side of the tank and prevents disarrangementwhen coupling the valve 12 or uncoupling the tank and the connection id.

The valve casing 12 is provided with friction rollers 15 extending to the interior of the casing, as shown in Fi 3, being: adapted for engagement with a va ve l6, s idable 1n the casing and provided with an upper chamber 17, and preferably-with a roller bearing pivotpin 18, that crosses the said chamber; and normally the valve 16 rests upon a suitable seat 19 from which it may be raised or forced to seat itself, through the medium of a float havin connections to be hereinafterset-forthw 'l. e valve casing 12 is provided with opposing upwardly extending members 20 and 20, that act as standar s.

lhe main stem 21 of-an operating arm B is located and ivoted between the standards ber of removable weiights 24 usually located upon a threadedro 25, and held in place .20 and 20, w ich stem is bifurcated at its bye. thumb nut26- or the -like; the number of weights employed being dependent on the difierent pressures-.ofcitywater plants.

. Thev shorter member 22 0f theo crating a'rm- B, is' provided. with a groove pulley i .27, that engages the under face or edge of the lever A at the rear of its fulcrum, so

' that said arm B is swung out to the position 'shown in dotted lines in Fig.- 3, when the said lever A is drawn downward to open the flushing valve A to permit of the inletvalve 16 being opened.

The pulley 27 is renderedadjustable by being mounted upon a forked slide 28 mounted on said member 22, as shown in Fig. 7, and

has a slot 29 therein, and a set screw 30 is passed through the slot.

The stem 21 of the arm B is pivoted on a,

pin 31. In connection with the main stem 21 of the operating arm B, a valve-controlling member 32 is provided, terminating at its lower end in a head 33, that extends beneath the main stem 21, having a rounded bottom face and a correspondingly curved erating arm B is vertically adjustable, so as nose 34 extending therefrom, as is illustrated in Fig. 3. The head 33 normally has such bearing upon a roller 35 at the upper end of the inlet or supply valve 16, as to keep the valve closed, as is also shown in Fig. 3. The valve-controlling member 32 of the opthepin, as is shown in Fig. 3. The shank or arm of the fork' 39 extends freely out.

through an openingin the side of the valve casing 12, asls shown in Fig. 8, and has interlockmg yet adjustable connection with the shank of. a socket 40, that carries the stem 41 of the float 42. The pivotal and adjustable connection between the two said parts 39 and 40, as is also best shown in Fig.

8, is effected by a suitable (pivot pin 43 passed through the parts 39 an 40, and throu h cars 44 at the sides of'the openin in t e casing, through which parts 39 and the pin-loosely extends, being secured to one of said ears, as is also shown in Fig. 8. The member 39'adi'jacent to its pivotal connection with the mem er 40,'and at a oint adjacent to the aforesaid pivot43, is ormed into a flat extension 45 having a segmental slot 46 produced therein, as-is lllustrated in Fig. 8

and an adjusting screw 47 is passed through said section 45 at' the slot 46, and is-threaded into the socket member 40, as is also shown in Fig. 8. Thus in the construction of said float connection, it will be observed that the parts or members 39 and 40 can be adjusted and held in adjustmenttoadmit of a greater or less amount of water being discharged from the tank, due to the inclination of the stem of the float, and that the said float iii rising and in dropping, will operate the inlet valve and 0 en the same, when the tank is comparative y empty, and will close the valve after the tank has received its proper supply of water. In addition to the aforesaid functions of the float 42, the said cock so' operates that should a leak occur at the flushing valve A, or at other parts of the tank, onlythat amount of water in the tank can escape, and no water can be admitted to the tank until the lever A is operated for another flushing operation. This action is accomplished as follows: A locking arm 48 is carried upward from the part 45 of the float member 39, having a bifurcated upper end 49 that carries a roller 50, which roller, when the float rises and the inlet valve 161's closed, engages the inner face of a tooth 51 at the under face of a latch lever 52 pivoted to the standard 20, for example, by a suitable pivot pin 53, and at the inner sidp face of this latch lever a substantially triangular lug 54 is formed, see Figs. 3 and 6, and a corresponding lug 55 is formed upon the lower portion of the main stem 21 of the operating lever B, in such manner that when the roller-bearing upper endof the operatingarm or lever is carried downward and'its lower end is swung out from between the standards 20 and 20, the latch-lever 32 havin been raised by the engagement of the r0 ler 50 with the tooth 51 on said latch lever, the lug 55 on the operatin arm will so engage with the lug 54 on the Tatch-lever 52 as to hold the operating lever in its tripped position, as shown in dotted lines in Fig. 3. At this time the flushing valve A is opened and float 42 gradually settles to the-- bottom of the tank A, and as'the locking arm- 48 is thrown backit disengages the latch lever 52, allowing the lug 54 to engage the lug 55 on the o crating arm Bwhenever the flushing lever A is pulled.

When the float 42 reaches the lowest position, or approximately so, th'e valve 16 is opened and water is admitted to the tank, the flushing valve A closing itself by suction in the usual manner. During the discharge of the water, the stem attachment for the float 42 retains the'inlet valve 16 in closed position, opening it as stated when the float is near the bottom of the tank. As. the float 42 ris'es, acam 56, adustable by means of a set screw 56 carrie by the locking arm 48, presses down the yoke section 58 of a lock lever C by assing through a slot 59 in said yoke section 58. The lock lever C is provided withv a weight 60 which assists in the operation. A suitable stop 61 is provided for the latch lever 52, as is shown in Fig. 4, and a likestop'may be provided for the lock lever C.

By the adjustment of the cam 56 throu h the set screw 56, the time of closing t e inlet valve may be regulated as desired. The yoke section 58 of the lock lever t, is pivoted to the standards 20 and 20 'in such manner that when the operating arm- B is carried to the angular position shown in dotted lines in Fig. and in fulllines in Fig. 4, and the lugs 54 and 55 are in looking engagement, the operating arm B cannot return to its normal, position until the yoke section 58 of the lock lever ,C is depressed from the position shown in Fig; 4 to the position shown in Fig. 3-. This position is assumed at or about the timethe float. 42 reaches its upper position. The yoke section 58 of the lock lever (J acts as an additional locking means to prevent the operating arm B from returning'to normal position before the proper time. I i

It is evident that when the parts are in.

the. position just stated, should there be any leakage at the flushing valve, or anywhere else in the tank, only that amount of water in the tank can escape, and that no more can enter until the flushing lever A is operated.
